Professor Miguel Tinker-Salas, an oft-quoted expert on Latin American political issues, has been quoted twice in recent media about Venezuelan President Hugo Chavez's treatment for cancer in Cuba. After earlier surgery in Cuba, Chavez has returned to the country for chemotherapy and people are speculating why. In an Associated Press article on Forbes.com, Tinker-Salas suggests he may have returned for continuity in treatment. In the Houston Chronicle, Tinker Salas says that Chavez opponents may see the return to Cuba as a sign of frailty, while it may help supporters rail around the president.
